Every time that I want to do a Layout, I'm getting a black layout preview then I can drop stuff on it, that's ok, but how can I change the size of that blank surface (xml). The question came because I set a folder layout-large and then when I add a new layout.xml to that folder it came with the same size, as a layout-normal, so I’ve something like that
(folder)layout
layout.xml
(folder)layour-large
layout.xml
Both file has the same physical or visible size, how can I increase the large one?
